Charlie Hunnam recently went naked for a Calvin Klein ad. The "Sons of Anarchy" actor star was seen making out with a Victoria's Secret model Doutzen Kroes in the racy print ad. In one of the shots, Hunnam is half naked and is nuzzling into Kroes neck while in another shot, Kroes is naked and is kissing Hunnam on the cheeks.

Apart from print ads the two were also seen indulging in some steamy love making scenes in the television commercial. The ad shows Hunnam and Kroes as naughty neighbours. The Pacific Rim star is seen gazing at Kroes through a window as the latter tries to seduce him.

Later the two touch each other passionately and show off their sizzling chemistry. Hunnam can clearly look suave in racy scenes, no wonder he was the first choice for Christian Grey in "Fifty Shades of Grey."

Meanwhile, Hunnam recently revealed that he almost had a nervous breakdown when he took the last minute decision to back out from the spicy film based on the bestselling novel by EL James.

"I just had like...frankly, something of a nervous breakdown. I just said, 'I can't... I can't ...,' to fail on such a grand scale - because Fifty's going to be massive, it's going to be huge. I really didn't want to fail on such a grand scale," said Hunnam of his decision to leave the film to US Weekly.

Reportedly when "Fifty Shades of Grey" was offered to him his schedule conflicted with "Sons of Anarchy" final season and the actor couldn't seem himself transition between the two very different roles. Hunnam was later replaced by Jamie Dornan.

"I'm sure he'll do a great job, "Hunnam had said to TMZ of Dornan when the latter was selected to play Christian on the celluloid, adding, "I don't really know his work, but I know Sam [Taylor-Johnson], the director, is amazing, and she has fantastic taste, so I'm sure he'll do a great job.

Hunnam is currently seen in FX's biker series "Son of Anarchy." The show is curretly running its last season.
